java - 在树集上增加值(value)

我读文字。我的文字是这样的

AYSE;SERDAR-9.8;EMRE-5.2;AYTAC-3.3
FATMA;OYTUN-8.8;ORKUN-7.5;ONUR-5.4;UMUT-4.4;BERK-3.3;CAN-3.2
DERYA;VELI-7.7;ALI-6.5;SUAT-6.0;YAVUZ-5.0;OYTUN-4.2;ORKUN-3.1
DILARA;DOGUS-8.8;VELI-7.4;ALI-6.5;SUAT-5.5;YAVUZ-3.1
BEGUM;SUAT-6.6;YAVUZ-5.1;OYTUN-4.3;ORKUN-4.0
BERIL;CANER-8.7;DOGUS-7.5;VELI-6.2;ALI-6.1;SUAT-5.8;YAVUZ-4.8;OYTUN-4.0
FUNDA;ORKUN-9.7;ONUR-8.3;UMUT-7.2;BERK-6.5;CAN-5.5
ISIL;AYTAC-8.3;CANER-7.4;DOGUS-6.5;VELI-5.5;ALI-5.4;SUAT-4.4;YAVUZ-4.0;OYTUN-3.9;ORKUN-3.5;ONUR-3.4;UMUT-3.2;BERK-3.1;CAN-3.0
ELIF;EMRE-7.4;AYTAC-6.1

ı无法将“ u.eleman”和“ u.uyum”值添加到“ treeset tSU”。当系统无法在tSU TREESET中看到它们时，它将提供内存地址。我想将所有这些添加到树集。我该怎么办..请帮助

最佳答案

当系统无法在tSU TREESET中看到它们时，它将提供内存地址。


不，它不打印内存地址。它以十六进制打印对象的类名称，@和哈希码-默认情况下，Object.toString()会执行此操作。

如果希望以不同的方式打印Uyum对象，请在类toString()中重写Uyum方法。
